Survey of Infection Prevention and Control (IPAC) Practices among Heart and Lung Transplant Centers
Bibliographic record
Abstract
Background. There is a perceived lack of standard practice on IPAC strategies among heart and lung transplant centers. Methods. A survey was performed of members of the American Society of Transplantation Infectious Diseases Community of Practice in 11/14 and 2/15 on their institutional IPAC policies after heart and lung transplantation. Results. A total of 40 providers from 29 transplant centers in the United States (22), Canada (2), Switzerland (2), South Korea (1), Ireland (1), and Turkey (1) responded to the survey. Of the 29 centers, only a minority provide HEPA filtered rooms (10.3% immediately post-transplant, and 3.4% when clinically indicated only). Likewise, a minority provide positive pressure rooms (all hospitalizations −3.4%, immediately post-transplant only −17.2%, when clinically indicated only −10.3%). The number of centers using HEPA filtered or positive pressure rooms did not differ between heart and lung transplant centers. 20.7% of the centers require additional hand hygiene beyond standard handwashing, such as use of gloves (10.3% at all times and 3.4%, immediately post-transplant). Measures beyond standard room cleaning were reported in 17.1% of centers, either immediately post-operatively or with clinical indication. About one third do not use dedicated small medical equipment for use in evaluating heart or lung transplant recipients. Majority of transplant centers does not allow plants or flowers in the units (65%). The majority (68.8%) does not prohibit the use of personal belongings in rooms and the majority does not allow animal companions (63%). Visitor age restriction varied from <5 years to <15 years. Lung transplant centers were more likely to recommend use of respiratory masks for patients when leaving hospital rooms (58%), as compared to heart transplant centers (48%). A third of lung transplant and over a quarter of heart transplant centers recommended respiratory mask use outside of the hospital, however duration varied from immediate post-transplant to at all times. Conclusion. This survey highlights differences in IPAC strategies among heart and lung transplant centers. Evidence-based guidelines addressing these practices are needed in an effort to standardize the approach in the care of this population. Disclosures. All authors: No reported disclosures.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
